You’ve probably often seen birds perched on power lines while you’re out and about. But why do they do it and why don’t they get electrocuted?
So far, scientists have found some fascinating reasons behind this behaviour.
Why don’t birds get electrocuted?
Firstly, it’s important to understand how electricity works. When electricity travels through conductors like wires, it encounters minimal resistance along its path.
The wires are made of copper which allows electricity to flow continuously.
As for the birds safety, electricity fundamentally relies on the movement of electrons. When a bird sits on a wire, both of its feet are in the same place at the same time which prevents electrons from passing through the bird’s body.
Since the electrons don’t pass through the bird, no current flows and the bird remains safe.
Why do birds choose to sit on power lines?
The reasons behind birds choice to perch on power lines can be diverse.
Warmth:
During cold weather, birds tend to sit on power lines because it warms their bodies. By sitting on the wires, their feet and bodies absorb some heat. helping them stay warm.
Avoiding predators:
Birds perch on power lines to stay away from predators. Power lines provide a safe vantage point allowing birds to keep an eye out for potential threats from above.
Food source:
Power lines offer birds a great view of their surroundings helping them spot insects and other prey more easily. This elevated position allows them to quickly swoop down and catch their meals.
Social interaction:
Some scientists believe that birds also sit on power lines to interact with each other. Especially for migratory birds sitting on power lines can provide an opportunity to reunite with their flock members during migration.
While birds don’t get electrocuted when perching on power lines, it’s essential to note that touching other parts of electrical infrastructure such as transformers or exposed wires can be dangerous for them. Overall, the behaviour of birds perching on power lines showcases their adaptability and resourcefulness in urban environments.
